Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Today, with the explosive growth of smart audio devices, consumers' demands for high-fidelity sound quality, low-power operation and compact design have become essential. Traditional AB-class amplifiers are increasingly unable to meet the strict requirements of TWS headphones, smart speakers, and in-car entertainment systems due to their low efficiency (only 30%-50%) and heat generation issues. System overheating, reduced battery life, and limited PCB space have become common problems for engineers.

Shenzhen Mingjiada Electronics Co., LTD., as a long-term partner of Infineon, fully supplies MERUS™ Class D audio amplifier chips. With breakthrough multi-level modulation technology, it helps you create the next-generation audio equipment that is "small in size, cold in operation, and high in fidelity"!

MERUS™ Class D audio amplifier, multi-chip module and discrete MOSFET/HEMT driver IC

Class D amplifiers with lower temperatures, smaller size and lighter weight create outstanding audio products

With its revolutionary multi-stage D-class amplifier IC, Infineon leads the pack in both power efficiency and power density. Listening, feeling and experiencing all contribute to achieving a clear tone. To ensure the presentation of audio amplifier performance, the development of Infineon MERUS™ products is based on three fundamental principles.

Power efficiency - Producing sound in the speaker rather than heating the surrounding environment

Integration - only its sound can be heard, but not its form. Shedding the cumbersome figure, it welcomes a new and delicate life

Quality - sturdy and flexible, not fragile and demanding

The Infineon product range encompasses fully integrated single-chip audio solutions, as well as discrete audio solutions that incorporate highly scalable amplifier driver ics and are combined with power MOSFETs. MERUS™, as a dedicated product series for Infineon Class D audio applications, has an output power range of 20 W to 2 kW per channel and can meet various design requirements.

As the number of audio channels in a single product increases day by day, conventional Class D amplifiers in compact applications are facing many challenges: low power efficiency, excessive heat generation (even at medium volume), and the need for bulky and expensive filters. The world's first Infineon multi-stage amplification technology reduces electromagnetic interference and out-of-band noise while improving power consumption. By eliminating or minimizing the use of filters, manufacturing costs can also be reduced, which helps to save design space.
